When you’ve got a hammer, everything looks like a nail, but the world starts to look more interesting if your hammer can change shape.
For the builders of a class of robots called modular self-reconfigurable robots (MSRR), shape-shifting is the first step toward endowing robots with an animal-like adaptability to unknown situations. “The question of autonomy becomes more complicated, more interesting,” when robots can change themselves to meet changing circumstances, said roboticist Hadas Kress-Gazit of Cornell University.

Elizabeth Blackburn’s work on telomeres, for which she was jointly awarded the 2009 Nobel Prize in Physiology or Medicine, has turned her into a socially minded scientist. In a keynote lecture at the 68th Lindau Nobel Laureate Meeting in June, Blackburn — a biologist at the University of California, San Francisco — called on scientists young and old to follow the same path: “Let’s use our scientific prowess to be more active, politically.”

Health researchers and workers use their training and the treatments available to them to prevent and treat illness. But they cannot bring their expertise to bear if they do not have the trust of the people that they are trying to treat.
This August, in the Democratic Republic of the Congo, communities in the midst of an Ebola outbreak continued traditional rural burial practices that include touching bodies, despite health workers’ advice on sanitary burials. Residents in the village of Manbangu burnt down a health centre and injured an Ebola health-care worker after one resident died of Ebola. Sometimes fear and misinformation drive even more violent behaviour: in a 2014 outbreak of the disease in Guinea, residents of the village of Womey killed a group of eight visiting health workers, journalists and government officials.

Every great bottle of wine begins with a humble fungal infection. Historically, winemakers relied on naturally occurring yeasts to convert grape sugars into alcohol; modern vintners typically buy one of just a few laboratory-grown strains. Now, to set their products apart, some of the best winemakers are revisiting nature’s lesser-used microbial engineers. Not all these strains can withstand industrial production processes and retain their efficacy—but a natural additive offers a possible solution, new research suggests.
